Answer:
Question is incomplete.
Assuming the below info to complete the question
You have a collection of n lockboxes and m gold keys. Each key unlocks at most one box. Without a matching key, the only way to open a box is to smash it with a hammer. Your baby brother has locked all your keys inside the boxes! Luckily, you know which keys (if any) are inside each box.
Detailed answer is written in explanation field.
Explanation:
We have to find the reachability using the directed graph G = (V, E)
In this V are boxes are considered to be non empty and it may contain key.
Edges E will have keys .
G will have directed edge b1b2 if in-case box b1 will have key to box b2 and box b1 contains one key in it.
Suppose if a key opens empty box or doesn’t contain useful key means can’t open anything , then it doesn’t belongs to any edge.
Now, If baby brother has chosen box B, then we have to estimate for other boxes reachability from B in Graph G.
If and only if all other boxes have directed path from box B then just by smashing box B we can get the key to box b1 till last box and we can unlock those.
After first search from B we can start marking all other vertex of graph G.
So algorithm will be O ( V +E ) = O (n+m) time.
Answer:
The first automatic digital computer has been designed by the English mathematician and inventor Charles Babbage. Babbage developed the Analytical Engine Plans for the mid-1830s.
Explanation:
- Babbage has developed the concept of a digital, programmable computer and was a mathematician, philosopher, inventor, and mechanical engineer.
-
Some regard Babbage as a "computer father"
-
The inventing of its first mechanical computer, the difference engine, is attributable to Babbage, which eventually resulted in more complex electronic designs, although Babbage's Analytical Engine is the main source of ideas for modern computers. He was described as the "prime" among the numerous polymaths of his century by his varied work in another field.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
You can submit your course work most often in a Word document. Because in the word document, you can insert text, numbers, images, charts whatever you want such as required for writing a book- easily.
The correct options to this question, that you should need to avoid using to create and submit course work are pages, numbers, and keynote.
Because while submitting the course work, you need to submit a complete word document, it is not required to you that you have to submit numbers, pages, or keynotes along with the course assignment. You can create a course assignment or project document in word and submit to your respective teacher. However, you can not create your course work using keynotes or pages, etc as given in the question.
